Engine Performance problem
2000 GMC Jimmy 6 cyl Four Wheel Drive Automatic 133000 miles
I just bought a used 2000 Jimmy 4w drive, and love it, but it's a gas guzzler (13-15 city, maybe 20 highway). I have already done or added:
a radiator flush - with new fluids
chemical engine clean - switching from oil to Mobil 1 synthetic oil.
added: (for the moment)
an oem oil filter
an oem gas filter
spent the cash for a K&N lifetime air filter!
I was ready to buy Bosh Platinum (due to advertising) but the man at Pep Boys is arguing heavily that I buy AC Delco, which are made for a "Jimmy" and won't "throw" off the "rest of the on board components" like a german plug with different specs might do.
anyhow -- what plugs do I get, and what else should to be done, and most importantly, what specific "best of the best" parts should I invest in to make the Jimmy "solid". I do small millage in city driving, some highway - an occasional up a mountain trip, but not very often.
I'm glad I got the K&N air filter. And now I desire a better than OEM everything.
I'm thinking of the Fram High Mileage oil filter for cars with more than 75000 miles. (Because of their advertising) but will it "improve" anything?
I'm not sure what fuel filter to use. (Or if I even need a better than OEM model).
I'm told that I don't need to concern myself with the oxygen sensors - since they are not moving parts -- and there are no warning lights, etc.
Now that I've cleaned the engine and switched to synthetic oil, I don't know if oil or gas additives work, or are necessary. Wonder about Fuel injector cleaners. And what products are "superior" [best for my Jimmy] like the K&n Filter seems to be.
And I intend to degrease the engine.
So, without asking you to take up a LOT of time, for the money I'm offering -- what's your best advice for a novice that is willing!
have the same problem?
